RolandP Hello Kingbob Yes, you can purchase an upgrade ticket with half fare reduction (½). You can upgrade it for a specific route, or a day. Also Supersaver class upgrades are possible: https://www.sbb.ch/en/tickets-offers/tickets/point-to-point-tickets-switzerland/class-upgrades-supersaver-class-upgrades/class-upgrade.html Kind regards, Roland
Kingbob Thank you. I took a look at the link. So I am clear. With the Swiss Travel Pass Flex, I should choose the Half Fare reduction to get a one day upgrade for one of my Flex days. Thank you again.
